'[0 a!! whom it may concern.'

Be it known that l, CARI. G iinrisox, a citizen of the United States,residing at Syracuse. in the count-y ot' Onondaga and State of New York,have invented certain new and awful Improvements in Ty )ell'ritingMachines, oi which the following is a specification.

Vl`his invention comprises various improvements in the carriage stopsand inargin rclease devices ot' typewi itiiig machines.

'lhe invention will be described in detail hereinal'ler reference beinghad to the accompanying drawing, in which,

Figure l is a top plan View, partly in section, of the margin rack,margin and carriage stops, and connected parts; Fig. 2 is a frontelevation of the same; Fig. 3 is a sectional View on the line A-A ofFig.v 1, .showing the connections from the vmargin rack to the linelocking mechanism, and Fi". l is a section on the line B-B of F ig. l,showing the connections for operating the bell and for releasing thecarriage from the margin stops.

Referring to the drawing, l indicates the rear portion of the top plateof the machine frame, and 2 indicates the back bar of the carriageframe. .l rock shaft 3 is journaled upon adjustable pivot screws etarranged in hearings 5 which are secured to the to plate of the machineat its right and le t-hand ends. Levers and i' are secured to the rockshaft 3 near its ends, and a margin rack bar 8 is secured to theforwardly projecting armsl 6 and 7 of said levers. The levers 6 and 7,and the rack har, normally rest in a horizontal position. as shown inFigs. 3 and 4, being supported on fixed points Sf. A rod or link t) ispivotally connected to the rear arm 7" of the lever 7 and to the freeend of a sub-lever l0, which is pivoted upon a stud' 1l secured in abracket. 1:3 depending from the top plate of the machine. This sub-leveris connected aty a point. intermediate of its ends to the upper end of alink t3, whose lower end is connected to a margin release key lc\cr ll.arranged atthe right side of thc machine and normally held in its raisedl position against a suitable stop h y a: lsprinj y l5. 'l'he link [23has a threaded joint lil, hy.; meansol' which the relation ofthe ke)vlever Il to the margin rack har may he regnhatcd, and the link J has aprojection 9, which.: when thilink is depressed, bears upon the l end ofthe hell hannner 1G and moves the hammer into position to ring the hellwhen .the link 9 is released and moves upward.

rl`he hell ll is mounted on an arm L of an adjustable lever 42% which ispivoted at 4lto en a bracket 45 of the main frame. The lcrcr -ll has aslot lo through which passes a. clamping screw 4T. l`he hell hammer it;is pivotcd at i8 in the free end of lever -t` andl is preferablyprovided with a light Aspring tf1 G5 to throw it against; the hell. ltwill he seen that. the slot and screw -lt and -tT provide means foradjusting the hell hammer or lever with relation to its operating means9'l without disturbing the rclat ion of the hell 70 hammer pivot to thebell. The stroke ot the bell hammer may thus he verl,i amvenientlyadjusted.

A rod or link 1T has its upper end pivoted to the rear arm (3b of thelever t3, and the 75 lower end of this rod has a longitudinal slot `1Tengaging a pin 18 upon the horizontal arm 19H of a bell crank lever 1t)which 1s pivoted upon a stud Q0 secured in a hanger 2l depemling fromthe top plate l. The ver- 80 tical arm 1t)b of said hell crank lever isarranged to operate the line lock mechanism, more particularly describedin a companion application. The slot 1T permits lost motion between therod 1T and the. hell crank 85 lever l5), so that the margin rack may beraised a sufficient distance to .sound the hell without operating theline lock mechanism, and when the rack is further elevated the line lockmechanism is operated by the movement of the bell crank lever 19, whichis then operatively engaged h y the rod 1T.

The margin rack 8 is graduated, as shown,

to correspond with the letter spacing of the machine, und is provided,on its rear edge,

with notches 22 arranged one leiter space apart. margin stop 23 isprovided upon the right-hand portion of the rack for regnlatin;r theleft-hand margin ot' the page of printed matter, and a `stop fl isarranged 100 npnir the left-hand portion of the rack to regulate theright-hand margin. This latter .stop when engaged hy a stop upon thecarriage. also causes the operation ol`v the bell and the line lockingmechanism. As shown,

each margin stop hanl a longitudinal slot or oroovc '25 throu'rh whichthe niarem rack rrr* extends. and thc lateral walls ot' this grooveflare outwardly in opposite directions from the central portion of thegroove, :is indi- 110 fav catetl bv the refcreia'e character L23". :sothat th tops maj,7 he ro'iml to a limitcfi extent in .i pivotal manne'upon1 `inarfgmrara bar. lach stop is provnlett vvitr :i moin 2li 5adapted to engage the notches ir he bar. and a snrine 25D nrrfingeilwithin the flaring; portion of lthe groove opposite said tooth, normalif Vholil l the tooth in one of the notchcb'iin the rack 'nai'. it virililie cviflent that brrockingthestopoasioconipress the springt, the tooth23 may be rr-lcaSi-ii anal the. .stop moveil to an)1 lc-i1 .il portionof the liar.
